Its very difficult for me to study these IBM (iSeries)machines
http://en.wikipedia.org/wiki/IBM_System_i, but slowly am getting some basic findings .
Two weeks back I got access to one online AS400 machine through internet . So learning RPGLE ,CL and basic commands we can practice in my UBUNTU.
just telnet pub1.rzkh.de
then can start WRKMBRPDM ( work with members)
